Gone, Gone, Gone by Hannah Moskowitz
There are so many effects coming to play here that I love: The fading into black. The abandoned shoes. The grainy image. (Yeah, it's meant to be like that. I didn't just upload a bad quality picture.)
For me, even the title choice is artistic: Gone, Gone, Gone. I don't even know what this book is about, but the cover and the title themselves make me want to read it, and, to me, that's what amazing covers are all about.
